I believe I did. But before replying, I'll try it again to be
sure... Yup, just what I remembered. Maybe *you* should read it
carefully:

SMTP error from remote mailer after HELO epitools.com:
host mail.weird.com [204.92.254.2]: 501-fatal error while validating 'HELO' host name 'epitools.com'.
501-connection rejected from ns.epitools.com remote address [66.166.77.34].
501-Reason given was:
501- No reverse DNS PTR for the remote address [66.166.77.34] has a hostname
501 matching 'epitools.com'

I don't know what that is supposed to mean, but fortunately your
rejection message is quite clear.

Coincidence? Sounds like you don't understand your own policies.
